Bosnian Bichaq

[gp]

a new addition to my collection but a strange one :

first the year 1879: 1 year after the conquering and annexation of Bosnia by Habsburg...not often seen
Secondly the style of the blade is more like the Ottoman yataghan (a wave-like type) compared to the later more dagger-like type ( almost European)
Third., the hilt, handle which has no similarity with the yataghan types ( sadle, ears, etc) but looks more like the joint-end of a bone being carved in a fancy "animalistic" decorated way...(?); never seen something like this but that doesn't mean anything...
Last but not least the decoration on the hilt / handle / grip clearly differs from other types which can be seen here in several threads.( with the exception of the 2 circles)

Have you seen or met this type before ? Do you have one in your collection? Can you advise or have knowledge about this one ?
